If you’ve ever wondered whether you could legally keep a lion in Wisconsin, you’re not alone — the question comes up more often than you might expect in a state that has historically had some of the loosest exotic animal regulations in the country. The answer today is far less permissive than it once was, and getting it wrong carries serious legal consequences at both the state and federal level.
Understanding where Wisconsin law ends and federal law begins is essential before you even consider this path. This guide walks you through every legal layer that applies — federal statute, state code, local ordinances, and the penalties that follow a violation.
Is It Legal to Own a Lion in Wisconsin
The short answer is no — not for new owners. The Big Cat Public Safety Act was enacted on December 20, 2022, to end the private ownership of big cats as pets and prohibit exhibitors from allowing public contact with big cats, including cubs. That federal law now applies in every state, including Wisconsin, and it effectively closed the door on new private lion ownership regardless of what state law says.
Wisconsin’s own regulatory history made it an outlier for decades. In the state of Wisconsin, residents are barred from owning wild animals that are native to Wisconsin, but as far as dangerous animals from outside the state, people were historically allowed to own those — including lions and tigers — with very little to any regulation, unless it was done at the local level. That landscape changed dramatically with federal intervention.
Important Note: Even if you find older sources suggesting Wisconsin has no exotic animal ban, federal law enacted in December 2022 now prohibits new private lion ownership nationwide. Always verify the current status of any law before acting on older information.
Wisconsin’s lion-related legal picture is now a layered one: federal law sets the floor, state law adds its own licensing requirements, and local ordinances can be even more restrictive. You need to understand all three levels before drawing any conclusions.
What Federal Law Says About Lion Ownership
Federal law is now the primary barrier to private lion ownership anywhere in the United States. The Big Cat Public Safety Act placed new restrictions on commerce in and possession, breeding, and use — including public contact — of certain big cat species referred to as “prohibited wildlife species,” to address threats to public safety posed by lions, tigers, leopards, snow leopards, clouded leopards, jaguars, cheetahs, cougars, and any hybrids thereof.
The law amends the Captive Wildlife Safety Act to prohibit the private possession of lions, tigers, leopards, cheetahs, jaguars, cougars, or any hybrid of these species. This prohibition is narrowly focused on pet big cats and exempts zoos, sanctuaries, and universities.
Before this law, the federal picture was inconsistent. Prior to the enactment of the Big Cat Public Safety Act, the United States had no federal law regarding the possession or breeding of big cats, except where there was a violation of another federal law, such as take under the Endangered Species Act or international trade contrary to CITES. That gap allowed states like Wisconsin to operate with minimal oversight for years.
Key Insight: The Lacey Act also plays a role. The Big Cat Public Safety Act revised requirements governing the trade of big cats under the Lacey Act to limit possession, breeding, and exhibition. The Lacey Act prohibits any person from importing, exporting, buying, selling, transporting, receiving, or acquiring big cats across state lines or the U.S. border.
A narrow grandfather clause does exist. The Act includes an exception for private individuals or entities who owned big cats before this law was enacted on December 20, 2022. If you are a private big cat owner, you may keep your prohibited big cat under this law, provided you had registered each big cat in your possession with the USFWS no later than June 18, 2023. That registration window is now closed. If you did not register a lion you owned before December 20, 2022, you are no longer protected by that exception.
Penalties under federal law are steep. Anyone who violates the law faces up to $20,000 in fines and up to five years in prison.
Wisconsin’s Laws on Owning a Lion
At the state level, Wisconsin’s approach to exotic animals has long been described as among the most permissive in the country. When it comes to the law on what kinds of animals you are allowed to possess, Wisconsin is one of four states that has had almost no regulations. However, that permissiveness has always applied more narrowly than many people assume.
Wisconsin law regulates the possession of and activities involving captive wildlife. Activities that are regulated include but are not limited to taking, transporting, selling, purchasing, introducing, stocking, releasing, hunting, exhibiting, propagating, and rehabilitating captive wild animals. These rules are codified under Chapter 169 of the Wisconsin Statutes.
Wisconsin wildlife laws require a license to take a wild animal from the wild or to import one into the state. A license is also required to exhibit, breed, rehabilitate, hunt, and/or purchase wild animals. Violations can result in fines, forfeiture, and/or imprisonment.
Wisconsin’s regulatory framework focuses heavily on native species. Non-native animals like African lions fell into a gray zone for years — the state did not explicitly ban them, but it also did not have a streamlined permit process for private pet ownership of big cats. There are technically no state-level laws regulating private ownership of exotic pets in Wisconsin; however, each city has its own ordinances. That gap is now largely irrelevant for lions given the federal prohibition, but it explains why Wisconsin attracted attention as a destination for exotic animal owners before 2022.
Pro Tip: If you are researching Wisconsin’s exotic animal rules for a species other than a big cat, contact the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) directly. DATCP notes that aside from the prohibited species it lists, it does not determine if it is legal to own a particular exotic animal species and strongly encourages you to contact officials at all levels of local government.

Permits and Requirements for Lion Ownership in Wisconsin
Because federal law now prohibits new private ownership of lions, there is no permit pathway in Wisconsin that would allow a private individual to acquire and keep a lion today. The question of permits is therefore relevant only to a very narrow set of circumstances: entities that qualify for exemptions under the Big Cat Public Safety Act, and the now-closed grandfather registration for pre-2022 owners.
For exempt entities, Wisconsin’s DNR does offer several licensing categories. According to the Wisconsin DNR, they offer several different licenses: a captive wild animal farm license, a nonprofit educational exhibit license, and the nonresident temporary exhibiting license. These are designed for facilities like accredited zoos, sanctuaries, and educational institutions — not private pet owners.
If you were importing any animal into Wisconsin from another state, an additional federal-state layer applies. An Animal Import Permit from the Department of Agriculture, Trade and Consumer Protection must be obtained prior to the import of any animal into Wisconsin from another state, province, or country.
| Entity Type | Can Possess a Lion? | Key Requirement |
|---|---|---|
| Private individual (new acquisition) | No | Prohibited by federal law (BCPSA) |
| Private individual (pre-Dec. 20, 2022 owner) | Only if registered | Must have registered with USFWS by June 18, 2023 (window closed) |
| AZA-accredited zoo | Yes | Federal exemption; Wisconsin DNR exhibit license |
| Qualified wildlife sanctuary | Yes | Federal exemption; must meet sanctuary standards |
| University / research facility | Yes, with conditions | Federal exemption; federal Animal Welfare Act registration |
It is your responsibility to follow all local, state, tribal, and federal laws and regulations regarding prohibited wildlife species. Registration under the Big Cat Public Safety Act does not constitute authorization to engage in any activity prohibited by such laws and regulations.
For context on how mountain lions are regulated across American states, the patchwork of laws before the BCPSA was similarly inconsistent — a reminder of why uniform federal standards were seen as necessary.
Local Laws That May Apply in Wisconsin
Even before the federal ban, Wisconsin cities and counties had begun filling the regulatory gap left by the state legislature. Local rules vary significantly across the state, and some are stricter than others.
The City of Milwaukee is one of the most restrictive. In the City of Milwaukee, there are ordinances in place. The city makes it illegal to own “any animal that is not domesticated.” That language would encompass lions and virtually all other exotic animals.
The City of Janesville takes a similar approach. Janesville prohibits owning all types of wild, exotic, or vicious animals, including venomous snakes, lions, monkeys, and alligators.
At the county level, some jurisdictions have created their own permit systems. Under the Sauk County Animal Control Ordinance, Chapter 27, an animal with vicious or dangerous propensities — including large wild animals — under the possession of any person residing within Sauk County jurisdiction will need a permit from the public health department. This can include specific animals such as apes, baboons, bears, cheetahs, crocodilians, elephants, hippos, hyenas, jaguars, leopards, lions, lynxes, monkeys, pumas, rhinos, sharks, snow leopards, tigers, wolves, and wolf-dog hybrids.
Wisconsin’s legislature has also provided a model ordinance framework for towns. Under the Wisconsin Legislature’s model harmful and exotic wild animal ordinance, no person may exhibit, possess, sell, or purchase an exotic or wild animal or harmful wild animal in the town without a written permit from the town board.
Common Mistake: Assuming that because Wisconsin has historically had lax state-level exotic animal laws, your city or county also has no restrictions. Many municipalities have independently enacted bans or permit requirements that are stricter than state law. Always check with your local government before drawing conclusions.
While your state may allow you to keep certain animals as pets, local laws can restrict ownership. Additionally, state laws are frequently changing in response to concerns for public safety and animal well-being. You should always double-check for any new or proposed state or local legislation.
Wisconsin has a diverse wildlife community worth exploring through legal means. You might be interested in the types of hawks in Wisconsin, the types of herons in Wisconsin, or the many butterflies in Wisconsin that make the state a rewarding place for wildlife observation.
Penalties for Illegally Owning a Lion in Wisconsin
The consequences of illegally owning a lion in Wisconsin operate on two tracks: federal penalties under the Big Cat Public Safety Act, and state-level penalties under Wisconsin’s captive wildlife and endangered species statutes. Violations at both levels can occur simultaneously.
Federal penalties are the most severe. Anyone who violates the Big Cat Public Safety Act faces up to $20,000 in fines and up to five years in prison. These penalties apply to possession, breeding, acquisition, transport, and any commerce involving a prohibited wildlife species outside the law’s narrow exemptions.
Wisconsin state penalties apply when state licensing or import rules are violated. Wisconsin wildlife laws require a license to take a wild animal from the wild or to import one into the state. A license is also required to exhibit, breed, rehabilitate, hunt, and/or purchase wild animals. Violations can result in fines, forfeiture, and/or imprisonment.
For violations involving endangered or threatened species — which may apply to lions listed under the federal Endangered Species Act — Wisconsin law carries additional consequences. Violation of the Act with regard to protected animal species may result in a $500–$2,000 fine for a taking, and a $2,000–$5,000 fine with nine months imprisonment for an intentional taking. Both incur the suspension of hunting license privileges.
Beyond fines and imprisonment, authorities can seize the animal. Any officer employed and authorized by the department, or any police officer of this state or of any municipality or county within this state, shall have the authority to execute a warrant to search for and seize any goods, business records, merchandise, or wild animal taken, employed, used, or possessed in violation of this section.
There are also practical consequences that extend beyond legal penalties. If an animal gets sick, trying to find a veterinarian is almost impossible. It is not a good life and it is not a natural life. Seized animals often end up in sanctuaries like Valley of the Kings in Sharon, Wisconsin, which houses animals surrendered or abandoned by private owners.
If you’re passionate about big cats and Wisconsin wildlife, consider supporting accredited sanctuaries or exploring the state’s remarkable native wildlife — from the types of spiders in Wisconsin to the types of dragonflies in Wisconsin and the types of finches in Wisconsin — all of which can be observed legally and responsibly in their natural habitat.
